| ○ | ○ | Article | Evaluation of solvent recyclability in fast microwave liquefaction with glycol ether of pine wood for preparation of lignocellulosic micro-fines | Lignocellulosic micro-fines (LCMFs) were prepared from pine wood meal by glycol ether liquefaction using microwave irradiation for 90 s. The recovery method and reusability of the solvent (glycol ether) for the liquefaction process were examined. When the volume of the dehydrated recovered solvent was compared with that of the original solvent, the recovery rate was about 97% and this recovery rate remained similar even when solvent recycling was repeated. IR spectrum of the dewatered recovered reagent was very similar to that of the virgin reagent. The yield and residual lignin content of LCMFs prepared by primary and secondary recycled solvents were almost the same as those obtained using virgin solvents. Similarly, no difference was found in the particle size distribution, crystallographic index, and chemical properties of these LCMFs. In conclusion, LCMFs can easily be prepared by rapid microwave irradiation with glycol ether. Furthermore, wood liquefaction for LCMFs using glycol ether is a very economical method because the solvent can be recycled very simply. | Kim, Kang-Jae; Ryu, Ji-Ae; Choi, Sa Rang; Eom, Tae-Jin | Kyungpook Natl Univ, Sch Forestry Sci & Landscape Architecture, Wood Sci & Technol, 80 Daehakro, Bukgu 41566, South Korea; Kyungpook Natl Univ, Dept Wood Sci & Technol, 80 Daehakro, Bukgu 41566, Daegu, South Korea; Kyungpook Natl Univ, Agr Sci & Technol Res Inst, 80 Daehakro, Bukgu 41566, Daegu, South Korea | Kim, Kang-Jae/K-3915-2019 | 35733947500; 57195239379; 57208283768; 13410809400 | tjeom@knu.ac.kr; | EUROPEAN JOURNAL OF WOOD AND WOOD PRODUCTS | EUR J WOOD WOOD PROD | 0018-3768 | 1436-736X | 78 | 4 | SCIE | FORESTRY;MATERIALS SCIENCE, PAPER & WOOD | 2020 | 2.014 | 29.6 | 0.17 | 2025-06-25 | 2 | 3 | PYROLYSIS; CELLULOSE; SPECTRA; BIOMASS | Ethers; Glycols; Liquefaction; Particle Size; Radiation Effects; Reagents; Ethers; Glycols; Irradiation; Lignocellulosic biomass; Liquefaction; Microwave irradiation; Particle size; Particle size analysis; Reagents; Recycling; Reusability; Economical methods; Liquefaction process; Recovered solvent; Recovery methods; Recovery rate; Residual lignins; Solvent recycling; Wood liquefaction; Solvents | English | 2020 | 2020-07 | 10.1007/s00107-020-01550-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Speech and music pitch trajectory classification using recurrent neural networks for monaural speech segregation | In this paper, we propose speech/music pitch classification based on recurrent neural network (RNN) for monaural speech segregation from music interferences. The speech segregation methods in this paper exploit sub-band masking to construct segregation masks modulated by the estimated speech pitch. However, for speech signals mixed with music, speech pitch estimation becomes unreliable, as speech and music have similar harmonic structures. In order to remove the music interference effectively, we propose an RNN-based speech/music pitch classification. Our proposed method models the temporal trajectories of speech and music pitch values and determines an unknown continuous pitch sequence as belonging to either speech or music. Among various types of RNNs, we chose simple recurrent network, long short-term memory (LSTM), and bidirectional LSTM for pitch classification. The experimental results show that our proposed method significantly outperforms the baseline methods for speech-music mixtures without loss of segregation performance for speech-noise mixtures. | Kim, Han-Gyu; Jang, Gil-Jin; Oh, Yung-Hwan; Choi, Ho-Jin | Naver Corp, Clova Speech, Seongnam Si, Gyeonggi Do, South Korea; Korea Adv Inst Sci & Technol, Sch Comp, Daejeon, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | Oh, Yung-Hwan/C-1915-2011; Jang, Gil-Jin/E-9360-2010 | 56981363500; 7102646102; 7402126180; 35073646600 | hangyu.kim@navercorp.com;gjang@kaist.ac.kr;yhoh@kaist.ac.kr;hojinc@kaist.ac.kr; | JOURNAL OF SUPERCOMPUTING | J SUPERCOMPUT | 0920-8542 | 1573-0484 | 76 | 10 | SCIE | COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;COMPUTER SCIENCE, THEORY & METHODS;ENGINEERING, ELECTRICAL & ELECTRONIC | 2020 | 2.474 | 29.6 | 0.29 | 2025-06-25 | 3 | 5 | Speech segregation; Speech pitch estimation; Pitch classification; Recurrent neural network; Long short-term memory; Bidirectional long short-term memory | SEPARATION | Bidirectional long short-term memory; Long short-term memory; Pitch classification; Recurrent neural network; Speech pitch estimation; Speech segregation | Acoustic variables measurement; Brain; Long short-term memory; Mixtures; Recurrent neural networks; Speech; Harmonic structures; Monaural speech segregations; Pitch estimation; Recurrent neural network (RNN); Simple recurrent networks; Speech segregation; Temporal trajectories; Trajectory classification; Continuous speech recognition | English | 2020 | 2020-10 | 10.1007/s11227-019-02785-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | Carbohydrate responsive element binding protein (ChREBP) negatively regulates osteoblast differentiation via protein phosphatase 2A Cα dependent manner | Carbohydrate responsive element binding protein (ChREBP) is a major transcription factor of lipogenesis regulated by glucose status in the liver. However, the function of ChREBP in osteogenic differentiation is unclear. The present study examined the role of ChREBP in osteoblast differentiation in MC3T3-E1 preosteoblast cell line. The mRNA expression of ChREBP, protein phosphatase 2A catalytic subunit-alpha (PP2A C alpha) and the osteogenic genes such as, DNA-binding protein inhibitor (Idl), runt-related transcription factor-2 (Runx2), and alkaline phosphatase (ALP) was measured by qPCR and RT-PCR. Runx2, ChREBP, and PP2A C alpha, protein levels were evaluated by Western blotting. ALP staining experiment was carried out to evaluate ALP enzyme activity, and a luciferase reporter assay was performed to analyze Runx2 transcriptional activity. Expression of ChREBP and PP2A C alpha did not change during bone morphogenetic protein-2 (BMP2)-induced osteoblast differentiation. Overexpression of ChREBP reduced the osteogenic genes (Runx2 and ALP) expression and ALP activity, while knockdown of ChREBP had the opposite effects. Overexpression of PP2A C alpha increased ChREBP expression, while inhibition of PP2A C alpha using okadaic acid not only inhibited the expression of ChREBP, but also restored the mRNA and protein expression of Runx2 and activity of ALP enzyme. These results demonstrate that ChREBP inhibits BMP2-induced osteoblast differentiation in a PP2A C alpha- dependent manner. | Kim, Kyeong-Min; Kim, Eun-Jung; Jang, Won-Gu | Daegu Univ, Sch Engn, Dept Biotechnol, Gyeongbuk 38453, South Korea; Daegu Univ, Res Inst Antiaging, Gyeongbuk 38453, South Korea; Kyungpook Natl Univ, Dept Immunol, Sch Med, Daegu 41944, South Korea | KIM, EUNJUNG/KFC-0377-2024 | 57190987288; 57213014281; 36948705500 | kkm97655@naver.com;ejkim4164@gmail.com;jangwg@daegu.ac.kr; | INTERNATIONAL JOURNAL OF BIOCHEMISTRY & CELL BIOLOGY | INT J BIOCHEM CELL B | 1357-2725 | 1878-5875 | 124 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CELL BIOLOGY | 2020 | 5.085 | 29.7 | 0.06 | 2025-06-25 | 2 | 1 | ChREBP; PP2A Ca; Osteoblast differentiation; BMP2; Ethanol | FATTY-ACID SYNTHESIS; BONE-FORMATION; GLUCOSE-HOMEOSTASIS; INSULIN-RESISTANCE; GROWTH-FACTORS; EXPRESSION; ETHANOL; ACTIVATION; ALCOHOL; CELLS | BMP2; ChREBP; Ethanol; Osteoblast differentiation; PP2A Ca | 3T3 Cells; Animals; Basic Helix-Loop-Helix Leucine Zipper Transcription Factors; Bone Morphogenetic Protein 2; Carbohydrates; Core Binding Factor Alpha 1 Subunit; Ethanol; Gene Knockdown Techniques; Gene Silencing; Inhibitor of Differentiation Protein 1; Mice; Okadaic Acid; Osteoblasts; Osteogenesis; Protein Phosphatase 2; RNA, Small Interfering; Up-Regulation; alcohol; alkaline phosphatase; bone morphogenetic protein 2; carbohydrate responsive element binding protein; DNA binding protein inhibitor; messenger RNA; okadaic acid; phosphoprotein phosphatase 2A; protein phosphatase 2A catalytic subunit alpha; transcription factor; transcription factor RUNX2; unclassified drug; alcohol; basic helix loop helix leucine zipper transcription factor; Bmp2 protein, mouse; bone morphogenetic protein 2; carbohydrate; inhibitor of differentiation 1; Mlxipl protein, mouse; okadaic acid; phosphoprotein phosphatase 2; Runx2 protein, mouse; small interfering RNA; transcription factor RUNX2; animal cell; Article; bone development; cell differentiation; controlled study; down regulation; enzyme active site; enzyme activity; enzyme inhibition; gene; gene expression; gene knockdown; gene overexpression; Id1 gene; lipogenesis; luciferase assay; MC3T3-E1 cell line; molecular biology; mouse; nonhuman; osteoblast; protein expression; protein function; real time polymerase chain reaction; regulatory mechanism; reverse transcription polymerase chain reaction; transcription regulation; Western blotting; 3T3 cell line; animal; drug effect; enzymology; gene silencing; genetics; metabolism; osteoblast; upregulation | English | 2020 | 2020-07 | 10.1016/j.biocel.2020.105766 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Control of conductive filament growth in flexible organic memristor by polymer alignment | This study investigates the dynamics for conductive filament growth in organic memristors from the viewpoint of the ionic transport by controlling the ordering of polymer molecules. Furthermore, we propose a simplistic and novel approach to improving the reliability of the devices by confining conductive filament growth. It is observed that conductive filament growth is varied with the polymer molecular ordering that governs the ion pathways. In the device with the aligned polymer electrolyte, conductive filament growth is realized only in a localized region due to the confinement of the ion pathways by the aligned polymer molecules. Our flexible organic memristor consisting of the homeotropically aligned polymer shows the reliable resistive switching characteristics and stable mechanical flexibility. This observed principle of conductive filament growth in the polymer electrolyte will provide a physical understanding of conductive filament growth in organic memristors, and useful guidelines for developing a new class of flexible neuromorphic electronics. | Park, Hea-Lim; Kim, Min-Hoi; Lee, Sin-Hyung | Seoul Natl Univ, Dept Mat Sci & Engn, 1 Gwanak Ro, Seoul 08826, South Korea; Hanbat Natl Univ, Dept Creat Convergence Engn, Daejeon 305719, South Korea; Kyungpook Natl Univ, Sch Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea | Lee, Sin-Hyung/ABD-6425-2022 | 55735654600; 38260922200; 57226880204 | haelim1017@snu.ac.kr;mhkim8@hanbat.ac.kr;sinhlee@knu.ac.kr; | ORGANIC ELECTRONICS | ORG ELECTRON | 1566-1199 | 1878-5530 | 87 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 3.721 | 29.7 | 1.61 | 2025-06-25 | 36 | 35 | Organic memristor; Resistive switching; Conductive filament; Polymer alignment; Liquid crystal polymer; Reliability | RESISTIVE SWITCHING CHARACTERISTICS; ARTIFICIAL SYNAPSE; MEMORY; TEMPERATURE; PERFORMANCE; DEVICES | Conductive filament; Liquid crystal polymer; Organic memristor; Polymer alignment; Reliability; Resistive switching | Flexible electronics; Memristors; Molecules; Conductive filaments; Ionic transports; Mechanical flexibility; Molecular ordering; Neuromorphic; Polymer electrolyte; Polymer molecule; Resistive switching; Polyelectrolytes | English | 2020 | 2020-12 | 10.1016/j.orgel.2020.105927 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Long-term thermal stability of NPB molecule under high-vacuum | During the deposition of organic light emitting diodes (OLEDs) using thermal evaporation, the purity of the deposition-source materials varies due to thermal stress, resulting in a reduced device stability. We developed an apparatus to evaluate the long-term thermal stability of deposition-source materials used in OLEDs, which is applicable even under high-vacuum conditions (below 10(-4) Pa)where the materials under test run out very quickly when exposed to temperature greater than 300 degrees C, which is above their deposition temperature. The goal of this work is to understand how thermal stresses imposed on OLED materials for a certain duration affect the material purity and, ultimately, the device performance. We used this apparatus to expose N,N'-Di(1-naphthyl)-N,N'-diphenyl-(1,1'-biphenyl)-4,4'-diamine (NPB), a commonly used hole-transport material for OLEDs, to thermal stresses for various durations. After maintaining the samples at 330 degrees C (380 degrees C) for 25 h (50 h), we performed high-performance liquid chromatography to analyze the material purity. In addition, OLEDs with a simple bilayer structure (NPB/tris(8-hydroxyquinoline)aluminum, Alq(3)) were fabricated from the heated samples to investigate how material impurities that are induced by thermal stresses affect the device stability. The results show that slight changes in the NPB purity caused by prolonged exposure to high temperatures significantly influence the electrical and optical characteristics of OLEDs fabricated from the heated NPB. | Shim, Seob; Kim, Hayeong; Choi, Eunmi; An, Jong-Ki; Kang, Goru; Kwon, Ohyun; Chung, Nak-Kwan; Kim, Jin-Tae; Yun, Ju-Young | Korea Res Inst Stand & Sci, Ctr Mat & Energy Measurement, Daejeon 34113, South Korea; Korea Univ Sci & Technol UST, Div Nano & Informat Technol Nanomat Sci & Engn, Daejeon 34113, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Sungkyunkwan Univ, Sch Mech Engn, Suwon 16419, South Korea; Samsung Elect Co Ltd, Suwon 16678, South Korea | 55812737000; 57212210088; 57207417930; 57191541166; 57191833835; 57188690621; 57188686805; 57203325070; 55696751000 | kimjt@kriss.re.kr;jyun@kriss.re.kr; | ORGANIC ELECTRONICS | ORG ELECTRON | 1566-1199 | 1878-5530 | 77 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 3.721 | 29.7 | 0.28 | 2025-06-25 | 7 | 5 | Organic light-emitting diodes; OLED materials; NPB molecule; Long-term thermal stability; Vacuum | SUBLIMATION POINT DEPRESSION; DEPOSITION; EMITTER | Long-term thermal stability; NPB molecule; OLED materials; Organic light-emitting diodes; Vacuum | Amines; Deposition; High performance liquid chromatography; Impurities; Molecules; Stability; Thermal evaporation; Thermal stress; Thermodynamic stability; Vacuum; Vacuum applications; 8-Hydroxyquinoline; Bi-layer structure; Deposition temperatures; Device performance; High-vacuum conditions; Hole transport materials; Optical characteristics; Organic light emitting diodes(OLEDs); Organic light emitting diodes (OLED) | English | 2020 | 2020-02 | 10.1016/j.orgel.2019.105446 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Development of Contact Lens-Shaped Crosslinked Amniotic Membranes for Sutureless Fixation in the Treatment of Ocular Surface Diseases | Purpose: To develop a new method of manufacturing contact lens-shaped crosslinked amniotic membranes (AMs) using glutaraldehyde (GA) and dialdehyde starch (DAS) as crosslinking agents. Methods: Amniotic membranes were placed on a curved plastic mold and crosslinked with either 4.5% DAS or 1% GA, after which their physical properties and biological safety were evaluated. Results: The tensile strength of the GA- and DAS-crosslinked samples was much increased compared with that of normal AMs. Neither crosslinking process affected AM transparency. Although the GA-crosslinked AM showed better enzymatic resistance, its physiological structure was severely damaged after the crosslinking process. On the other hand, compared with the GA-crosslinked AM, the DAS-crosslinked AM showed higher growth factor concentrations and better biocompatibility, similar to normal AMs. In addition, the DAS-crosslinked AM was effective in the recovery of corneal epithelial wounds and was well maintained over 3 days without decentration or degradation on the ocular surface in human subjects. Conclusions: Contact lens-shaped AMs were successfully prepared with crosslinking agents. Crosslinking with DAS did not affect the structural properties or biological activ- ity of the AMs, and the improved mechanical properties helped the AM to maintain its curved shape. This crosslinking method allowed us to transplant AMs into patients' eyes without sutures. Translational Relevance: Sutureless fixation of contact lens-shaped AMs would be very convenient and safe for the treatment of corneal surface disease. | Yi, Soojin; Huh, Man-Il; Hong, Hyeonjun; Yoon, Donghee; Park, Han Sang; Kim, Dong Sung; Kim, Hong Kyun | Kyungpook Natl Univ Hosp, Biomed Inst, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Pohang Univ Sci & Technol POSTECH, Dept Mech Engn, Pohang, South Korea | Kim, Hong Kyun/ITT-7758-2023; Kim, Dong-Seong/AAI-9774-2021 | 56783537100; 18634206800; 57008620000; 57201671265; 57216917215; 55742938500; 57218260940 | okeye@knu.ac.kr; | TRANSLATIONAL VISION SCIENCE & TECHNOLOGY | TRANSL VIS SCI TECHN | 2164-2591 | 9 | 6 | SCIE | OPHTHALMOLOGY | 2020 | 3.283 | 29.8 | 0.54 | 2025-06-25 | 5 | 6 | amniotic membrane; crosslinking; dialdehyde starch; sutureless fixation | DIALDEHYDE STARCH; TRANSPLANTATION; COLLAGEN; LAMININ; LINKING | Amniotic membrane; Crosslinking; Dialdehyde starch; Sutureless fixation | collagenase; epidermal growth factor receptor; glutaraldehyde; ketamine; proxymetacaine; sodium borohydride; somatomedin; transforming growth factor beta1; xylazine; amnion; animal experiment; animal model; animal tissue; Article; band keratopathy; basement membrane; biocompatibility; biosafety; chemical burn; clinical article; collagen degradation; cornea thickness; cross linking; elasticity; female; HCE cell line (cervical adenocarcinoma); histology; human; human cell; male; neurotrophic keratopathy; nonhuman; observational study; ocular surface disease; optical coherence tomography; pilot study; scanning electron microscopy; slit lamp microscopy; surgical technique; sutureless technique; tarsorrhaphy; tensile strength; tissue regeneration; visual acuity; wound healing assay; Young modulus | English | 2020 | 2020-05 | 10.1167/tvst.9.6.12 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficacy of modified radical prostatectomy technique for recovery of urinary incontinence in high-grade prostate cancer | BACKGROUND: This study was conducted to evaluate predictive factors of urinary continence recovery after radical prostatectomy (RP) for high-grade prostate cancer (PCa). METHODS: A total of 241 patients with high-grade (Gleason Score 8 or 9) PCa who underwent RP in a single Korean center between January 2011 and May 2018 were retrospectively reviewed. Urinary continence was defined as no pads use. Urinary continence was evaluated at 1, 3, 6, and 12 months after RP. Univariate and multivariate analyses were performed to determine the predictive factors of urinary continence recovery after RP. RESULTS: The mean age was 67.6 +/- 6.4 years, and the mean PSA was 18.7 +/- 21.1 ng/dL. A total of 197 (81.7%) patients underwent nerve-sparing RP, and 198 patients (822%) were continent 1 year after RP. Multivariate analysis showed that the age (odds ratio [OR]=1.091 [1.015-1.1721, P=0.018), Body Mass Index (BMI)(OR=1.227 [1.057-1.4241, P=0.007), and modified surgical technique (OR=0.109 [0.044-0.267], P<0.001) were independent factors for predicting urinary continence recovery after RR. CONCLUSIONS: Younger age, low BMI, and modified surgery were independent predictors of urinary continence recovery after RP in patients with high-grade PCa. These findings may help surgeons to give pre- and postoperative advice to patients with high-grade PCa about urinary continence recovery after RP. | Chung, Jae W.; Kim, Sang W.; Kang, Ho W.; Ha, Yun S.; Choi, Seock H.; Lee, Jun N.; Kim, Bum S.; Kim, Hyun T.; Kim, Tae H.; Yoon, Ghil S.; Kwon, Tae G.; Chung, Sung K.; Yoo, Eun S. | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Urol, Daegu, South Korea; Chungbuk Natl Univ, Chungbuk Natl Univ Hosp, Coll Med, Dept Urol, Cheongju, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Urol, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Pathol, Daegu, South Korea; Kyungpook Natl Univ, Joint Inst Regenerat Med, Daegu, South Korea | ; Kim, Tae/B-9921-2013; Kim, Soo-Yeon/ADR-9663-2022; Kim, Young-Bo/AAR-8052-2021 | 35204798500; 57219871166; 35757703900; 35487226400; 9742645500; 16301364600; 57202817150; 55739531300; 57797823600; 57204691355; 15073765400; 35200555500; 7006609239 | uroyoo@knu.ac.kr; | MINERVA UROLOGICA E NEFROLOGICA | MINERVA UROL NEFROL | 0393-2249 | 1827-1758 | 72 | 5 | SCIE | UROLOGY & NEPHROLOGY | 2020 | 3.72 | 29.8 | 1.04 | 2025-06-25 | 10 | 10 | Prostatic neoplasms; Prostatectomy; Urinary incontinence | ASSISTED LAPAROSCOPIC PROSTATECTOMY; CONTINENCE RECOVERY; PRESERVATION; EXPERIENCE | Prostatectomy; Prostatic neoplasms; Urinary incontinence | Age Factors; Aged; Body Mass Index; Female; Humans; Male; Middle Aged; Neoplasm Grading; Postoperative Complications; Prostatectomy; Prostatic Neoplasms; Recovery of Function; Republic of Korea; Retrospective Studies; Urinary Incontinence; prostate specific antigen; aged; androgen deprivation therapy; Article; body mass; cancer grading; cancer staging; cohort analysis; computer assisted tomography; controlled study; cystography; follow up; Gleason score; human; human tissue; lymph node dissection; major clinical study; male; modified radical prostatectomy; nerve sparing radical prostatectomy; nuclear magnetic resonance imaging; paralytic ileus; postoperative complication; prostate cancer; prostatectomy; retrospective study; robot-assisted prostatectomy; surgical technique; urine incontinence; wound dehiscence; age; cancer grading; convalescence; female; middle aged; pathology; postoperative complication; procedures; prostate tumor; prostatectomy; South Korea; urine incontinence | English | 2020 | 2020-10 | 10.23736/s0393-2249.20.03633-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | An intuitive and simple technique for accurate insertion point selection and precise Poller (blocking) screw insertion | Although indirect reduction with intramedullary (IM) nailing is the gold standard for long bone fractures, IM nailing in meta-diaphyseal fractures often results in malalignment. Placement of Poller (blocking) screws is an attractive and useful technique in these situations; however, the selection of accurate placement points and the placement process itself are often complicated. This paper proposes an intuitive, simple, and clear technique for selecting the location of Poller screw placement that can be used in either the anteroposterior or lateral view regardless of the fracture type and discusses techniques for Poller screw placement that enable displacement correction. | Yoon, Yong-Cheol; Oh, Chang-Wug; Oh, Jong-Keon | Gachon Univ, Trauma Ctr, Orthoped Trauma Div, Coll Med, Incheon, South Korea; Kyungpook Natl Univ Hosp, Dept Orthoped Surg, Daegu, South Korea; Korea Univ, Guro Hosp, Dept Orthoped Surg, Coll Med, 148 Gurodong Ro, Seoul 08308, South Korea | Oh, Chang-Wug/AAO-4602-2021; Yong-Cheol, Yoon/HPD-8077-2023 | 37082544400; 22135834200; 7402155046 | jkoh@korea.ac.kr; | ARCHIVES OF ORTHOPAEDIC AND TRAUMA SURGERY | ARCH ORTHOP TRAUM SU | 0936-8051 | 1434-3916 | 140 | 10 | SCIE | ORTHOPEDICS;SURGERY | 2020 | 3.067 | 29.9 | 0.41 | 2025-06-25 | 6 | 6 | Long bone shaft fracture; Meta-diaphysis; Malalignment; Poller screw | SHAFT FRACTURES; INTRAMEDULLARY; FEMUR | Long bone shaft fracture; Malalignment; Meta-diaphysis; Poller screw | Bone Screws; Fracture Fixation, Internal; Fractures, Bone; Humans; Article; computer assisted surgery; diaphysis; fracture; human; image processing; long bone; metaphysis; patient selection; priority journal; surgical approach; surgical technique; bone screw; devices; fracture; osteosynthesis; procedures | English | 2020 | 2020-10 | 10.1007/s00402-020-03398-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Review | Regional Hyperexcitability and Chronic Neuropathic Pain Following Spinal Cord Injury | Spinal cord injury (SCI) causes maladaptive changes to nociceptive synaptic circuits within the injured spinal cord. Changes also occur at remote regions including the brain stem, limbic system, cortex, and dorsal root ganglia. These maladaptive nociceptive synaptic circuits frequently cause neuronal hyperexcitability in the entire nervous system and enhance nociceptive transmission, resulting in chronic central neuropathic pain following SCI. The underlying mechanism of chronic neuropathic pain depends on the neuroanatomical structures and electrochemical communication between pre- and postsynaptic neuronal membranes, and propagation of synaptic transmission in the ascending pain pathways. In the nervous system, neurons are the only cell type that transmits nociceptive signals from peripheral receptors to supraspinal systems due to their neuroanatomical and electrophysiological properties. However, the entire range of nociceptive signaling is not mediated by any single neuron. Current literature describes regional studies of electrophysiological or neurochemical mechanisms for enhanced nociceptive transmission post-SCI, but few studies report the electrophysiological, neurochemical, and neuroanatomical changes across the entire nervous system following a regional SCI. We, along with others, have continuously described the enhanced nociceptive transmission in the spinal dorsal horn, brain stem, thalamus, and cortex in SCI-induced chronic central neuropathic pain condition, respectively. Thus, this review summarizes the current understanding of SCI-induced neuronal hyperexcitability and maladaptive nociceptive transmission in the entire nervous system that contributes to chronic central neuropathic pain. | Kang, Jonghoon; Cho, Steve S.; Kim, Hee Young; Lee, Bong Hyo; Cho, Hee Jung; Gwak, Young S. | Valdosta State Univ, Dept Biol, Valdosta, GA 31698 USA; Harvard Med Sch, Boston Childrens Hosp, Dept Ophthalmol, Boston, MA 02115 USA; Daegu Haany Univ, Coll Korean Med, Dept Physiol, Daegu 42158, South Korea; Daegu Haany Univ, Coll Korean Med, Dept Acupuncture Moxibust & Acupoint, Daegu 42158, South Korea; Kyungpook Natl Univ, Sch Med, Dept Anat, Daegu 41944, South Korea | Gwak, Young/AAL-2232-2021 | 55556257100; 57197837720; 57205024859; 22938054300; 7403936455; 7801687907 | jkang@valdosta.edu;Steve.Cho@childrens.harvard.edu;hykim@dhu.ac.kr;dlqhdgy@dhu.ac.kr;hicho@knu.ac.kr;ysgwak@dhu.ac.kr;hjcho@knu.ac.kr; | CELLULAR AND MOLECULAR NEUROBIOLOGY | CELL MOL NEUROBIOL | 0272-4340 | 1573-6830 | 40 | 6 | SCIE | CELL BIOLOGY;NEUROSCIENCES | 2020 | 5.046 | 29.9 | 0.68 | 2025-06-25 | 38 | 40 | Spinal cord injury; Neuropathic pain; Hyperexcitability | DORSAL-HORN NEURONS; REDUCES MECHANICAL ALLODYNIA; PRIMARY SOMATOSENSORY CORTEX; THALAMIC VPL NEURONS; AXONAL REGENERATION; OXIDATIVE STRESS; GRACILE NUCLEUS; 5-HT3 RECEPTOR; ROOT GANGLION; BILATERAL HYPEREXCITABILITY | Hyperexcitability; Neuropathic pain; Spinal cord injury | Animals; Chronic Pain; Humans; Neural Inhibition; Neuralgia; Neurons; Organ Specificity; Spinal Cord Injuries; brain cortex; brain stem; dorsal root; human; limbic system; medulla oblongata; nerve cell excitability; nerve cell membrane; neuropathic pain; nociception; nonhuman; priority journal; Review; spinal cord dorsal horn; spinal cord injury; synaptic transmission; thalamus; animal; antibody specificity; chronic pain; complication; metabolism; nerve cell; nerve cell inhibition; neuralgia; pathophysiology; physiology; spinal cord injury | English | 2020 | 2020-08 | 10.1007/s10571-020-00785-7 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Copper(II) complexes containing N′-aromatic group substituted N,N′,N-bis((3,5-dimethyl-1H-pyrazol-1-yl)methyl)amines: Synthesis, structures, polymerization of methyl methacrylate and ring opening polymerization of rac-lactide | A series of Cu(II) complexes, [LnCuCl2] (L-n = L-A-L-F), supported by N'-aromatic-group-substituted N,N-bis ((3,5-dimethyl-1H-pyrazol-1-yl)methylamine ligands have been synthesized. Variations of substituents at the ortho position of the aniline moiety influenced the solid-state structures of these complexes. The X-ray structures of [LnCuCl2] (L-n = L-A-L-C and L-F) revealed that ligands are coordinated in a N,N,N-tridentate fashion to Cu(II) center and adopted a distorted square-pyramidal geometry, while [LDCuCl2] with N,N-bidentate coordination adopts distorted tetrahedral geometry. These complexes were capable of polymerizing methyl methacrylate (MMA) in the presence of modified methylaluminoxane (MMAO), with [LFCuCl2] displaying the highest activity (2.81 x 10(4) g PMMA (mol Cu)(-1)h(-1)). Regardless of ligand architecture, syndio-enriched PMMAs have been furnished with a slightly broader polydispersity index (PDI). Additionally, the in situ generated dimethyl derivatives, polymerized rac-LA and furnished PLA with mediocre heterotacticities at room temperature. Importantly, the catalytic efficiencies of the Cu(II) complexes studied have been found to be influenced by the steric and electronic properties of ligand. (C) 2020 Elsevier Ltd.

| ○ | ○ | Article | Synthesis, structure and photoluminescence properties of naphthalene-based chiral zinc(II) complexes | Two novel chiral zinc(II) complexes containing naphthalene moieties, namely [Zn(CMN)Cl-2] (1) and [Zn (CBN)Cl-2] (2), were obtained through the reaction of zinc(II) chloride with, respectively, (1R,2R)-N-1-(naphthalen-2-ylmethyl)cyclohexane-1,2-diamine (CMN) and (1R,2R)-N-1,N-2-bis(naphthalen-2-ylmethyl)cyclohexane-1,2-diamine (CBN) in ethanol. The ligands CMN and CBN were characterized via infrared, nuclear magnetic resonance and absorption spectroscopic analyses. As regards to the two complexes, a comprehensive single crystal X-ray diffraction investigation showed that in both cases the zinc (II) ion is surrounded by two N atoms of CMN/CBN and two chloro groups, and has a distorted tetrahedral structure, though 2 also contains an additional naphthalene group. The photo-physical properties of 1 and 2 were examined based on their electronic absorption and photoluminescence spectra. Both complexes exhibited ultraviolet emissions (both at 335 nm in CHCl3; 336 and 385 nm for 1 and 337 nm for 2 in their solid states) under 278-298 nm excitation. (C) 2020 Elsevier Ltd.

| ○ | ○ | Article | Activated Carbon-Metal Organic Framework Composite for the Adsorption of Contaminants of Emerging Concern from Water | A composite adsorbent (CMOF) based on in situ growth of MIL-100Fe (MOF) within the macro- and mesopores of a Darco-KB-G activated carbon (AC) was prepared for the efficient adsorption of a set of contaminants of emerging concern (CECs), namely, caffeine (CFN), carbamazepine (CBZ), clofibric acid (CA), 10,11-epoxycarbamazepine (Ep-CBZ), naproxen (NPX), o-desmethylnaproxen (o-DMN), paraxanthine (PXN), and salicylic acid (SA), from water. The properties of the composite and that of the parent materials were evaluated via X-ray diffraction, scanning electron microscopy, nitrogen porosimetry, thermal gravimetric analysis (TGA), and X-ray photoelectron microscopy. Mass balances indicate that the composite contains about 46 wt % MOF, while a comparison of pore size distributions and TGA corroborated that the vast majority of the crystalline material resides within the macro/mesopores of the AC. Zeta potential measurements revealed that the acid media used during the in situ growth of the MOF resulted in a CMOF surface charge profile (isoelectric point (IEP) = similar to 3.2) that is generally more negative than that of the MIL-100(Fe) (IEP = similar to 4.2) and the nonacid treated AC (IEP = similar to 5.5). Single and multicomponent CEC equilibrium adsorption tests were performed at room temperature, neutral pH conditions, and low CEC concentrations (similar to mu g L-1). Single component adsorption data show that the composite adsorbs 10-fold more CEC molecules compared to the MOF alone, with a selectivity that increases as follows: CA < SA < o-DMN < PXN < NPX < CFN < Ep-CBZ < CBZ. The effect of competition among the CECs on the adsorption capacity of CMOF was not as significant, only about 9% smaller compared to single component adsorption data. Uptake improvements seen in the CMOF appear to be the result of interactions based on a combination of hydrophobicity (from the AC core) and enhanced electrostatic level forces as well as pi-complexation and pi-pi stacking interactions. | Munoz-Senmache, Juan C.; Kim, Sewoon; Arrieta-Perez, Rodinson R.; Park, Chang Min; Yoon, Yeomin; Hernandez-Maldonado, Arturo J. | Univ Puerto Rico, Dept Chem Engn, Mayaguez, PR 00681 USA; Univ South Carolina, Dept Civil & Environm Engn, Columbia, SC 29208 USA; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | ; Park, Chang Min/CAA-8506-2022; Yoon, Yeomin/KDP-2253-2024; Hernandez-Maldonado, Arturo/I-6288-2012 | 57207915316; 57201422323; 56764447700; 57209588953; 7402126688; 6601966346 | arturoj.hernandez@upr.edu; | ACS APPLIED NANO MATERIALS | ACS APPL NANO MATER | 2574-0970 | 3 | 3 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2020 | 5.097 | 30.1 | 1.59 | 2025-06-25 | 38 | 42 | metal organic framework; composite adsorbent; in situ crystal growth; contaminants of emerging concern; water remediation | PERSONAL CARE PRODUCTS; WASTE-WATER; AQUEOUS-SOLUTIONS; CURRENT KNOWLEDGE; PLANT UPTAKE; REMOVAL; PHARMACEUTICALS; MIL-100(FE); POLLUTANTS; DROUGHT | composite adsorbent; contaminants of emerging concern; in situ crystal growth; metal organic framework; water remediation | Activated carbon; Adsorption; Crystal growth; Crystalline materials; Fourier transform infrared spectroscopy; Organic polymers; Organometallics; Pore size; Salicylic acid; Scanning electron microscopy; Thermogravimetric analysis; X ray diffraction; Carbamazepine; Clofibric acid; Composite adsorbents; Contaminants of emerging concerns; In situ crystal growth; In-situ growth; Iso-electric points; Mesopore; Metalorganic frameworks (MOFs); Water remediation; Amides | English | 2020 | 2020-03 | 10.1021/acsanm.0c00190 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Antioxidant potential of non-oil seed legumes of Indonesian's ethnobotanical extracts | This study investigated the in vitro antioxidant properties (DPPH, ABTS, CUPRAC and FRAP), total phenolic content and flavonoid content of extracts from three non-oil seed legumes (Phaseolus lunatus red and white, and Canavalia ensiformis), local edible seeds from Indonesia, obtained using different solvent system (distilled water, 70% ethanol, and 100% ethanol). The variety of legume was a major source of variation in the phenolic contents, flavonoid content and antioxidant activity. HPLC analysis of the non-oil seed legume extracts identified gallic acid, epicatechin and coumaric acid. Among the varieties of non-oil seed legume extracts, the phenolic content varied from 15.21-38.60 mg gallic acid equivalents/g dry weight and the flavonoid content was 11.73-24.61 mg catechin equivalents/g dry weight. The antioxidant activity of the extracts suppressed the reactive oxygen species (ROS) generation and cellular damage induced by UV-B in HaCaT cells. These results showed that antioxidant activity (1.83-19.42% of inhibition DPPH; 2.99-37.29% of inhibition ABTS; 0.20-2.47 mu M CUPRAC value; and 0.96-1.10 mu M of FRAP value) of extracts possessed strong radical scavenging activity as well as inhibited ROS generation in a dose-dependent manner without showing any cytotoxicity. Collectively, the data presented that antioxidant of the extracts have potent antioxidant activity and decreasing ROS generation in HaCaT cells. It can be intimately used as alternative criterion for antioxidant and antiradical activities that can be utilized as a functional food and nutraceutical ingredients. (C) 2020 The Author(s).

| ○ | ○ | Article | Effects of a dianion compound as a surface modifier on the back reaction of photogenerated electrons in TiO2-based solar cells | The TiO2 films were modified with a dianion compound, 1,2-ethanedisulfonic acid disodium salt (ESD), to give a negative charge (ethane sulfonate anion) on the TiO2 surface, i.e., TiO2-O-SO2-CH2-CH2-SO3-), and effects of repulsion between the negative charge and ions (I-3(-)) of the electrolyte on the performance of dye-sensitized solar cells (DSSCs) were investigated. The reference device without any modification showed a power conversion efficiency (PCE) of 9.89%, whereas for the device with ESD(20)-TiO2/FTO, which was prepared by soaking bare TiO2/FTO in an ESD solution for 20 min, the PCE was increased to 10.97%, due to an increase in both short-circuit current (J(SC)) and open-circuit voltage(V-OC). It was verified from the measurements of electrochemical impedance, open-circuit voltage decay and dark current that the enhancement in the J(SC) and V-OC values was attributed to the reduced back reaction between photoinjected electrons and 13 ions, resulting from the presence of the ethane sulfonate anions on the TiO2 surface.
